Vehicle data sticker
Explanation of the PR. numbers (factory codes) on vehicle data sticker
Various brake systems are installed depending on engine and equipment level. These are identified by the PR. numbers (they are also known as factory codes).
Example of a vehicle data sticker
In this example the vehicle is equipped with the following brakes:
- Arrow 1 - Rear brakes - 1KE
- Arrow 2 - Front brakes - 1ZM
The vehicle data sticker is located as follows:
- Vehicles up to 03.00: In spare wheel recess
- Vehicles from 04.00 (Only Jetta vehicles): Next to spare tire wheel well, near left rear wheelhouse
- In service booklet
The following table explains brake numbers. These are important for the combination of brake calipers/brake discs and brake pads.
